Vision
In the retina, light first hits the pigmented layer because
the pigmented layer protects the neural layer. True or
false. If false, explain your answer.
When light passes through the eye in high intensity
& large amounts, the __________ will constrict, as
the __________ contracts.
The posterior cavity is filled with a fluid called
__________ while the anterior cavity is filled
with __________. .
Glaucoma is a condition where __________
(fluid) secreted by the __________ stops draining
via the __________ , causing excess
pressure in the eye.
Not all visual information goes to one area in the
brain. Some go to the __________ to regulate
__________.
Which of the following statement(s) is (are) correct?
Check all that apply.
a.The fovea centralis is where vision is least sharp
b.The macula contains only rods
c.The optic disc is where vision is the most sharp
d.The fovea centralis is in the center of the path of light
Hearing and Balance
The process of hearing begins when sound enters the
__________ .
In what area of the cochlea will low pitched sounds be
detected?
Which is the last structure to vibrate in this sequence?
Malleus round window stapes incus oval window
Tony gets sick easily on rollercoasters. Would closing his
eyes help him avoid this? Explain your answer.
As you go UP in an elevator, what is the mechanism
involved in the perception of upward movement?
a. Otolithic membrane moves downward as a result of
gravity, causing hair cells to bend and produce an action
potential that is transmitted to the brain
b. Otolithic membrane moves posteriorly as a result of
gravity, causing hair cells to bend and produce an
action potential that is transmitted to the brain
c. Otolithic membrane moves anteriorly as a result of
gravity, causing hair cells to bend and produce an action
potential that is transmitted to the brain
d. Otolithic membrane does not move and there is no
action potential transmitted to the brain
What is the difference between low and high frequency
sound waves traveling through the cochlear duct
endolymph?
a. Low frequency sound waves are shorter than high
frequency sound waves and, as such, travel further
b. Low frequency sound waves are longer than high
frequency sound waves and, as such, travel shorter
distances
c. Low frequency sound waves are longer than high
frequency sound waves and, as such, travel further
d. Low frequency sound waves are shorter than high
frequency sound waves and, as such, travel shorter
distances
Where are the receptors monitor rotational movement of
the neck located?
